The lab develops new quantum devices by controlling the quantum states of electrons traveling through solids.

AboutAbout the lab
Merging quantum technology and condensed matter science
Yamamoto Lab conducts research on building quantum electronic devices based on techniques for controlling and transmitting quantum degrees of freedom in solids.
Its experiments include controlling, one electron at a time, the quantum states of electrons traveling through semiconductor microstructures, and transmitting and controlling new quantum degrees of freedom in atomically thin materials.
The lab elucidates how quantum coherence spreads and the physics of quantum correlations, in order to establish guiding principles for quantum devices.
The lab also aims to use advanced quantum technology to solve problems in condensed matter science from a microscopic perspective.
Key terms
- Quantum coherence
- The property of a quantum superposition state being maintained. It is easily lost through interaction with the surroundings.
- Electron wave packet
- A localized lump of waves that travels together within a certain range when an electron is viewed as a wave.
- Quantum simulation
- A method of using an easily controllable quantum system to reproduce and study the behavior of another quantum system that is difficult to calculate.

*Illustrative imageQuantum Computer Based on Electron Wave Packets
The lab performs experiments like those in quantum optics, but with electrons traveling through solids. By encoding quantum information in electron wave packets and passing them repeatedly through the same quantum circuit, it aims to realize a large-scale quantum computer built from relatively small hardware.
*Illustrative imageStrongly Correlated Quantum Simulation
The lab aims to quantitatively evaluate quantum many-body systems that are difficult to calculate, using dynamical quantum simulation with easily controllable semiconductor microstructures, and to elucidate universal properties of spin lattice systems.
